Subject: Remove gpu_refresh_rate configuration option

Changing it makes emulation inherently inaccurate. It also had a wrong
default value (30, whereas the real system has a refresh rate of 60 Hz)
which, even if changed, would continue to be used unless people manually
removed it from their config files.
